SPECIFICATION forming part of Letters Patent No. 699,429, dated May 6, 1902. Application filed August 17, 1901- Serial No. 72,430. (No model.)

To [LZZ whom it may concern:

Be it known that I, CORNELIUS WEANER, a citizen of the United States, residing at Defiance, in the county of Defiance and State of 5 Ohio, have invented a new and useful Heating-Stove, of which the followingis a specification.

My invention is an improved heati ng-stove; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

One object of my invention is to effect improvements in the construction of the casing of a heating-stove whereby a flue for the r smoke and heated products of combustion is formed integrally with the side walls of the casing, which due traverses the casing around the combustion-chamber formed therein and serves to conduct the smoke and heated prod- 2o nets of combustion from the combustionchamber to the smoke-pipe and to increase the efficiency of the stove as a heater by utilizing the heat of the said hot air from the inferior-f the stove, together with the other products of combustion.

A furtherobject of my invention is to pro vide an air-heating flue which is disposedwithin the said integrally-con structed smokeflue to draw air into the same, heat the air, and discharge the same when heated into the room or apartment in which the stove is located.

In the accompanying drawings, Figure l is a sectional perspective view of a heating- 3 5 stove constructed in accordance with myim provements. Fig. 2 is a horizontal sectional view of the same, taken on a plane intersecting the smoke and hot-air flues.

The stovebody or casing 1 maybe of any preferred size and shape. The side walls are reinforced at their lower portions around the fire-box where they contact with the burning fuel, and their upper portions are separated to form a smoke-flue. Preferablyin practice the side walls comprise one or more thicknesses of sheet or plate metal, the outer sheet or plate being indicated at 2 and the inner sheet or plate being indicated at 3. The upper portions of the said sheets or plates are outset laterally to separate them,'as at 4, to

and products of combustion to pass into the said smoke-flue from the combustion-chamber of the stove, and the said smoke-flue at its opposite end communicates with a collared opening 7 where the usual stovepipe Sis attached.

It will be understood that the smoke, hot air from the interior of the stove, and other products of combustion will be caused to pass from the combustion-chamber thereof through the smoke-flue 5, which encircles the stove, before escaping into the stovepipe and that the said smoke-fine 5 will materially increase the efficiency of the stove as a heater by retarding the passage of the hot air, smoke, and heated products of combustion from the stove and utilizing the same in the heating of said flue 5.

As here shown the plates or sheets 2 3 are formed at their upper and lower sides with outturned flanges 9, which are engaged by and bear against the top and bottom of the stove. The said top and bottom of the stove are flanged, respectively, as at 10 11, to engage the outturned flanges of the outer sheet or plate 2. I also provide an air-heating flue 12. The same is here shown as formed of a single piece of sheet metal, is disposed in and extends throughthe smoke-flue 5, and is suspended from and attached to the top of the stove, as at 13. One end of the said air-heating flue communicates with an air-intake opening 14 in the top or bottom of the stove, and the other end of the said air-heating flue communicates witha collared discharge-opening 15 in the top of the stove at a point proximate to the collared opening 7, to which discharge-opening 15 is attached an ascending pipe 16 of suitable length to create a draft through the said air-heating flue and cause air to be drawn into the same from the room to circulate through the said air-heating flue and be discharged therefrom in a heated condition through the pipe 16.

The latter is disposed on one side of the smoke-pipe 8, so that the heat of the latter is also utilized in heating the pipe 16 and the air that passes through it. Said pipe 16 may either discharge into the same room in which the stove is located or may lead to another room.

It will be understood that the air which passes through the air-heating flue 12 will be heated by the hot air, smoke, and other heated products of combustion which pass from the combustion-chamber of the stove through the smoke-flue 5, in which said air-heating flue is disposed.

Having thus described my invention, I claim- 1. A heating stove having side walls,with their lower portions, around the fire-box, reinforced and their upper portions, which surround the combustion-chamber, separated to forma smoke-flue which passes around the combustion-chamber, said smoke-fine communicating with the interior of the stove and With the smoke-exit thereof, substantially as described. Y

2. A heating-stove having a smoke-flue formed with the side walls thereoflsaid smokeflue passing around the stove, communicating with the interior thereof and with the smokeexir, and an air-heatin g flue disposed within the said smoke-flue and depending from the top of the stove, the latter having an air-intake opening at one end of said air-heating flue, and a discharge-opening at the opposite end thereof, proximate to the smoke-exit, substantially as described.

3. A heating-stove having side walls with their lower portions, around the fire-box, reinforced and their upper portions, which surround the combustion-chamber, separated to
